14, and 18 (i.e., steric resistance on neighboring rings) make heptacene derivative 4 especially resistant to photooxidation. It persists for weeks as a solid, for 1-2 days in solution if shielded from light, and for several hours in solution when directly exposed to both light and air. Heptacene derivative 4 has been fullycharacterized. It possesses a small HOMO-LUMO gap of 1.37 eV.
The present invention is directed towards a new class of semi-conducting nonacene derivatives. These compounds are all soluble species and they all possess superior resistance to oxidation as compared to their counterparts that lack the substitution patterns disclosed herein.
